Abstract In the present work, Cr 2 C and N MXenes are stacked to conform 2D heterostructures. The structural, electronic, magnetic properties were further investigated. Two stackings treated; first, on top of N, second, is C. most favorable configuration C/Cr with a vertical distance 2.35 Å. antiferromagnetic alignment evidences possible bias exchange effect. MXene preserves its ferromagnetic behavior changes layer polarization form bottom conserves intrinsic as antiparallel. Electronic evidence metallic behavior. Although in heterostructure comparable van der Waals interaction, charge density maps electron local function indicate interaction at interface, meanwhile difference exhibits transfer interface heterostructure. new that emerge from it could be interesting spintronics community due their applications information storage devices.
